Kubernetes for Developers

Overview of this book

Kubernetes is documented and typically approached from the perspective of someone running software that has already been built. Kubernetes may also be used to enhance the development process, enabling more consistent testing and analysis of code to help developers verify not only its correctness, but also its efficiency. This book introduces key Kubernetes concepts, coupled with examples of how to deploy and use them with a bit of Node.js and Python example code, so that you can quickly replicate and use that knowledge. You will begin by setting up Kubernetes to help you develop and package your code. We walk you through the setup and installation process before working with Kubernetes in the development environment. We then delve into concepts such as automating your build process, autonomic computing, debugging, and integration testing. This book covers all the concepts required for a developer to work with Kubernetes. By the end of this book, you will be in a position to use Kubernetes in development ecosystems.

Summary


In this chapter, we started with looking at the Pod lifecycle and status details in depth, expanding to show multiple ways of revealing relevant details, and describing what Kubernetes does beneath the covers while running your software. We then looked at the feedback loops that your program can provide with liveness and readiness probes, and reviewed examples of enabling those in both Python and Node.js. Following on from the probes and how your code can interact with Kubernetes cleanly, we looked at the common cases for startup and initialization, and graceful shutdown.

In the next chapter, we look at how to use Kubernetes and open source to provide basic observability for your applications, specifically monitoring and logging.
